On this day, "JFK gave best speech of his life, {June 10, 1963}, at American University:"

1. JFK outlined a plan to curb nuclear arms and a route for world peace.

Widely considered one of the most powerful speeches Kennedy delivered, he not only outlined a plan to curb nuclear arms, but also "laid out a hopeful, yet realistic route for world peace at a time when the U.S. and Soviet Union faced the potential for an escalating nuclear arms race."

In the speech, Kennedy announced his agreement to negotiations "toward early agreement on a comprehensive test ban treaty" (which resulted in the Nuclear Test-Ban Treaty) and also announced, for the purpose of showing "good faith and solemn convictions", his decision to unilaterally suspend all U.S. atmospheric testing of nuclear weapons as long as all other nations would do the same. Noteworthy are his comments that the United States was seeking a goal of "complete disarmament" of nuclear weapons and his vow that America "will never start a war".

The world might be a different place if JFK had lived and been successful with this plan.

I believe this speech may have been a part of why he was murdered months later.
